Since I could not find any IPAs of ManiaDrive for iOS I compiled it myself from source.
Compilation was done on a Power Mac G4 running MacOS 10.5.8 with the Apple iPhoneOS 2.2.1 and Raydium R888 iPhoneOS SDK.
Tested working on iOS 5.1.1 - iOS 10.3.3 (32bit) but needs a fast device to run smoothly.
This archive contains 2 IPAs; a full version containing assets from the PC game and a lite version which contains lower resolution assets which make it perform better on slower devices like an iPad 2.
Keyboard input doesn't work. Use gyro controls to drive.
The game is not very optimized for touchscreen devices and has some rendering issues. It should be considered alpha quality.
